Product Features and Performance
Reliable electrical insulation realizes effective isolation between battery modules and lowers short circuit risks for energy storage systems.
High tensile, flexural and impact strength delivers stable load bearing performance for large size thin separator plates.
Ultra low 0.12% molding shrinkage guarantees high dimensional accuracy and consistent assembly for battery separators.
HDT ≥200 ℃ provides efficient thermal barrier effect against abnormal battery temperature rise.
UL94-V0 flame retardancy (LOI≥33%) slows thermal runaway propagation and enhances overall battery pack safety.
Low water absorption keeps stable performance under variable temperature humidity; moderate flowability suits one shot molding of large thin wall separators.
Supported by in house BMC production lines for stable bulk supply of new energy energy storage projects; formula customization available.
Applications
Energy storage battery box separators, power battery module partition plates, insulating separators inside energy storage PACKs, lithium battery fire barrier components, insulating partition plates for energy storage cabinets, structural isolation parts of new energy battery packs.
